Colour Consistency and Shade Variation Control
topic
Knitted fabric colour consistency is controlled by maintaining consistent stitch length and fabric weight within each dye lot, monitoring yarn batch consistency through spectrophotometric fibre colour measurement before production, and managing machine-induced fabric weight variation that causes within-lot shade variation after dyeing, with spectrophotometric shade assessment of dyed fabric samples against standard using CIE deltaE colour difference measurement.
Role
Prevents the between-roll and within-roll shade variation in knitted fabrics that is the primary cause of garment assembly colour mismatch and customer rejection in cut-and-sew garment production, with colour consistency management requiring coordination of yarn sourcing, machine setting control, and dye lot management to maintain the fabric weight consistency that is the primary determinant of dye depth uniformity.
